I discovered by accident (just before we left for Mexico) that one of my favorite comic artists, Jon J. Muth, has been writing and/or illustrating children's books for several years. I took all these out of the library yesterday (I particularly like Zen Shorts so far):
The Three Questions
Old Turtle and the Broken Truth
Come On, Rain
Batman's Dark Secret
Muth's medium is watercolour, he also painted Moonshadow and Dracula for Marvel Comics.
